Description
To bridge the gap between conventional X-ray tubes and large-scale X-ray generation facilities, we have developed a Desktop Hard X-ray Source. This device provides higher X-ray intensity compared with traditional X-ray tubes while maintaining advantages of compactness, low cost, and ease of operation. The device consists of three main components: an injector, a beam transport line, and a storage ring. In this system, the electron beam generated by the injector is resonantly injected into the storage ring, where it circulates at high speed. During circulation, the electron beam repeatedly collides with a metallic micro-target installed inside the vacuum chamber, thereby generating X-rays. To achieve a more compact configuration while ensuring improved beam quality, an electron cyclotron accelerator is employed as the injector. This accelerator offers benefits such as small size and high microwave power efficiency. To ensure precise and stable operation of the device, a dedicated measurement and control system has been designed. The software framework of this system is built on Debian 12 and EPICS 7, integrating all device control and data processing into EPICS IOCs and establishing interconnections among relevant PVs. An OPI has been developed based on Phoebus to support system operation. In addition, machine learning techniques have been explored for integration into the control system to further enhance the intelligence and accuracy of control strategies.
